M ATTORNEYS are meshed with a worm 56 on a trans1n1s.

sion shaft. 57. The shaft', 57 has xedl mounted thereon a second wormgear whee 58, the teeth whereof mesh with the thread of a worm 59 on atransmission shaft 60. The shaft 60 is suspended in bearings 61 pendentfrom the Hoor of the ear or vehicle, as seen best in.Fig. 1 of thedrawings. The outer end of the shaft 60 is furnished with a sprocketwheel 62, which is operatively con nected by means of a sprocket chain63 with a relatively small sprocket .wheel 64 on the carrying axle 65 ofthe car or vehicle;

The wheels 64 and 62, the worms 59 and 56, the wheels 58 and 55, thewheel 52 and the wheel 51 al1 constitute a train of gears, arranged to=relatively reduce the speed transmitted from the axle 65 to the shaft49,

'to produce a relatively slow speed ou the` -shai't 49 as compared tothe speed of the .axle 65. It willbe understood that the ratio may be*ylargely varied by altering the relative sizes of any of the w eelsconstituting the chain above indicated. l

and 72 are adapted to be engaged by abeve/l,...4 gear wheel 73', whichwheel is slidably The sleeves 47 and 48. are supported by, androtatively mounted upon plungers 66 and 6?. The plungers 66 and 67 arenonrotatively mounted in the case 23, and are connected at the innerends by a square loop 68, withwhich loop said plungei's may beoptionally pivotally or rigidlv connected. At the outer ends offeach ofthe plungers, theyv are provided with push-heads-69 and 70. as bestshown in Fig. 3 of the drawings.

The'sleeves 47 and 48'have each rigidly attached thereto, at the endthereolbevel gear wheels 71l Vand v72.- The gear wheels 71 mounted uponthe upper end 'oflthe shaft 49, being suitably-splined or keyed theretoto "rotate therewith.V The hub of the wheel 73 yis channeledy to? fit ablock 74,bv which said wheel is lifted or depressed. The block 74normally rests on the thick portion 75 of a tongue extended from the endof the thrust bar 76.A The tongue is provided with a thin ortion .77connected with the thick portion yy-meaus of inclines78. lThe inclines78, as

'shown LestV in Fig. 6 of the drawings, are

disposedlat opposite sides of a rectangular opening 104 formed in thetongue to straddle the shaft 49. The thrust bar 76 is furnished at theouter end thereof with a knob handle 79. provided to be manually engagedfor adjusting-the bar 76. The tongue, at

that when the operator grasps the handle 7 9 and withdraws the rod 76,the thin portion 77 of the tongue passes under the block 74.

The block 74 and the wheel 73 connected therewith are then lowered bythe springs 82, until the wheel 73 is disengaged from ,the wheels 7l and72. In this position, the

indicator mechanism' is at rest. Prior to engaging the wheels 71, 72 and73, the operator presses on on'e of the heads 69 or 70 to adjust theclutches 83, 84,' 85 and 86 to operate ithe pulleys 87, 88, 45, 89,90-and 46,

.which pulleys and clutches are bestI seen in Fig. 3 of the drawings.

As above stated, the pulleys'45 and 46 are operatively connected withthe pulleys 41 andv 42 on the shaft 40. When the plungers 66 and 67 'aredisposed as showin in Fig. 3 of the drawings, the clutch 84, fixedlymounted on the plunger 66 by a pin 91, operatively engages the pulley45. By the same operation, thelclutch 86 which is fixedly mounted on theplunger 67 by meansof the pin 91 is ,moved out of engagement with thepulley 46. This arrangement insures the drive of the roller 30 to feedthe ribbon 12 in the di -rection indicated by the arrows in Fig. 2

of the drawings. It will be understood that if the reverse drive of theribbon 12 is. de-

sired, the push-head 70 is thrust inward to effect the engagement of theclutch 86 with the pulley 46, and the disengagement of the clutch 84with. the p ulley 45.

The pulleys 87 and 88 and 89 and 90 are i arranged in pairs, and areoperatively connected by'means of belts 92, 93, 94 and 95 withjp'ulleys96 and 97 and with pulleys 98 and 99. The belts 93 and 95 are reversed.,

being Vthereby arranged to transmit a -rei verserotary direction todrums 100 and 101 upon which the pulleys 97 and 99 are respectivelymounted.

The drums 100 and 101 cvzorr'espond in i shapel and construction withthedrums 19l and 20, and are mounted' directly beneath said drums 19-and20in paired relation thereto'but in reversed direction as far-as thetaper is concerned, that is, the small end A of the drum 100 is disposedbelow the large 'end of the drum 19, and the small end of the drum 101is disposed below-the large end of the drumv 20. The drums 19, 20, 100and 101 are similarly groved or threaded.

Each pair of drums is operatively connectedby belts 102 and 103.` Thepower driving the drums 19 and 20 is thus transmitted AAend thereof tothe other, and in relatively reverse'drections lengthwise of the case23.

From the foregoing, it will be seen that ifthe ribbon 12 is being drivenin the direction indicated by Fig. 2 of' the drawings,- the belt`103 ismoving toward the small end of the drum 20 and toward `the large end ofthedruin y101. Theresult of this action is l that the rotation of thespool 14- is being gradually increased as the diameter of the woundribbon 12 thereon is being gradually decreased. In a similar manner, thebelt 102 is being moved by the thrust on the drums 19 and 100 toward thelarge end of the drum 19 and the small end ofthe drum 100, therebyyrelatively diminishing the transmitted speed of rotation of the spool13. By this method, provisionjs made for `the gradually increasingperipheral speed of the roll of ribbon12-on one of said-spools, and the.correspondingly decreasing peripheral speed of alie-*roll on the otherof said spools.
